Fire crews had earlier warned locals who could smell smoke to keep windows and doors closed, but the smoke has dissipated.

Earlier there were reports of explosions at the site of the fire.

Local councillor Paul Tully said thick black smoke rose hundreds of metres into the air.

"There's very thick acrid plumes of smoke, but just when you think it might be dying down a little the plumes just come back up a little bit and into the sky towards Camira," he said earlier on Sunday evening.
